INVENTOR Mt/EKA vfaww/l/a L 5? ATTORNEYS PROOF-OF-PURCHASE LABEL FIELD OF THE INVENTION BACKGROUND OF THE INVENTION Manufacturers of consumer products often attempt to increase their sales by providing coupons or labels affixed to their goods which can be redeemed or used to purchase additional goods at a reduced price.

There are certain types of promotional programs where the promoting company does not in fact care if the person receiving the benefits of the promotion have already purchased their product. For example, in attempts to sell products one may wish to reduce the price of the product by a few pennies to induce consumers to buy. Often this is done by attaching a coupon or label to the product which can be used to buy a second product of the same manufacturer or a second package of the same product. In this type of promotion, the manufacturer may, in fact, be willing to sell the item at the reduced price to any purchaser. Therefore, he is not particularly concerned whether or not the labels or coupons are in fact proof of prior purchase.

If, however, a promotional campaign is employed wherein a valuable right is given to a consumer upon proof-of-purchase of a particular product, great care must be taken to insure that those consumers exercising these rights in fact have purchased the product. If this is not done, a promoter may find himself dispensing goodsin return for coupons or labels which in fact do not evidence sales.

When a lid, a bottle cap, or portion of a container is available to use as proof-of-purchase, a fair degree of assurance can be had that the bearer of the bottle cap, lid or container portion has in fact derived it through a purchase. When a label, however, is used, no such assurance can be had. For example, labels can be easily removed from tin cans or glass bottles while sitting on the shelves in a supermarket. U.S. Pat. No. 814,592 which issued to H. B. Duane on Mar. 6, 1906 recognizes the need for a reliable proof-of-purchase label but offers only a label which can still be ripped off in the store. Certain types of containers, for example aerosol cans, do not in fact have labels on them at all. The decorative and informative information previously applied to containers by labels are printed directly onto the aerosol cans.

Therefore, it is an object of this invention to provide a proof-of-purchase label which in fact insures that purchase of a promotors product has been made.

It is a further object to provide a proof-of-purchase label which is simple but cannot easily be removed in a supermarket without destroying the label.

It is a further object of this invention to provide a proof-of-purchase label which can be used on products which do not normally bear labels.

BRIEF DESCRIPTION OF THE INVENTION With these and other objects in view, the present invention contemplates a package in which an item has a label affixed thereto by an adhesive which will release the item when subjected to a predetermined physical stimulus.

In one embodiment, the label has a portion separated from the rest of the label by perforations. This area is afiixed to the package by the stimulus responsive adhesive while the remaining portion if affixed to the package by an adhesive which is nonresponsive to that stimulant.

DETAILED DESCRIPTION OF THE INVENTION Referring now to FIG. 1, we see a container 10 such as an aerosol can having an outer surface area 11. In FIG. 2, we see a label 12 made from a paper having a high wet strength and having a portion 13 thereof separated from the remainder of the label 12 by perforations 14 and 16. The label 12 has normal trademark and instructional material printed thereon, for example, in the area designated 17. The portion 13 of the label 12 may have printed matter on both sides thereof.

The label 12 is applied to the container 10 to form a unit as shown in FIG. 3. The portion 13 of the label 12 may be used for promotional purposes as a proof-ofpurchase label. The printing on the outside of the portion 13 may contain instructions, for example, on how to remove the proof-of-purchase label without destroying it. In one embodiment, the label 12 has an adhesive on the back side of the portion 13 thereof which is soluble in hot water. Such an adhesive may be a latex or textrine adhesive. These adhesives would hold the label 12 to the container 10 as seen in FIG. 3. It should be noted that since the portion 17 is adhesively aflixed to the container 10, an attempt to merely remove it from the container 10 will result in mutilation and therefore destruction thereof. It should be noted that the portion 13 of the label 12 has small perforations thereacross to aid in bringing that portion 13 of the label 12 to the container 10 insuring that an improperly removed label will be mutilated.

In this embodiment to remove the portion 13 from the container 10, one need only to run hot water over the package shown in FIG. 3, specifically over the portion 13. The hot water, for example water over 90 F, will melt and/or dissolve the soluble adhesive thereunder. Then, one may easily remove the portion 13 breaking the perforations 14 and 16. Since the label 12 has high wet strength, there is no fear that the label will be ripped in the process.

In a second embodiment, the label 12 has an epoxy adhesive on the back side thereof in all areas except behind the portion 13. The label 12 is then affixed to the container as shown in FIG. 3. A see-through sheet of material, for example, a high wet-strength, see-through paper having perforations thereacross is adhered on top of the label 12 by the adhesive which is soluble in hot water. This clear sheet may then be removed as outlined above by running it under hot water leaving the label 12 exposed so that the portion 13may easily be removed along the perforations 14 and 16. In either of these embodiments, the printing on the opposite side of the portion 17 can be read after being removed from the container 10. For example, a promoter may wish to provide instructions as to where to mail the label to receive an item.

It should be understood that if the label 12 were not properly affixed to the container 10, a person merely wishing to have the proof-of-purchase label without purchasing the goods could merely remove the label 12.

It should be understood that other physical stimulus such as the application of common solvents such as lighter fluid, ammonia, liquid detergents or the like could be used to distinguish between two adhesives holding two portions of a label such as label 12 against the container such as container 10. For example, a proof-of-purchase label on a vinegar bottle might require the vinegar to remove the label. In this way, further assurance can be had that the vinegar had been purchased and opened. One can appreciate that while removing a label from anitem on the shelf in a store can be done rather easily, it would be much more conspicuous to either open a bottle of vinegar and apply it to the label or more difficult still to find a source of warm water for removing the label.

In certain circumstances due to either the material from which a container is made or the contents therein, a particular physical stimulus may not be applicable to that particular container. For example, certain types of plastic containers cannot withstand particular types of solvents so that a proof-of-purchase label could not be employed by merely applying that solvent to the label.

Referring now to FIG. 4, we see a container 21 having an outer surface 22. A relatively strong sheet of material such as mylar 23, shown in FIG. 5, is applied and held by an adhesive such as epoxy to the container 21. An outer surface 24 of the mylar has an adhesive applied thereto soluble in warm water. A proof-ofpurchase label 26, made from a weaker sheet of material shown in FIG. 6 is applied atop the surface 24 and is and the container 21. The epoxy adhesive will not release and the mylar will provide protection for the container 21 while the water soluble adhesive will release the proof-of-purchase label 26. In this embodiment again, printed matter can be on the outer surface 24 of the mylar 23 having trademark and instructional material thereon, while the proof-of-purchase label 26 may have instructional and other material printed on both sides thereof.

It should be understood that again other physical stimulus such as common-solvents can be employed to differentiate between the two adhesives binding the proof-of-purchase label 26 to the mylar strip 23 and the mylar strip 23 to the container 21.

It should be understood that other material such as tin foil and the like can be used to protect the container 21 instead of the mylar.

It should be understood that while the invention has been described with reference to particular embodiments thereof, numerous others will become obvious to those of ordinary skill in the light of this disclosure.
